**v4.22.002** TTNL02 - Thermal transient with phase change
======================================================================

**Summary:**

This elementary test makes it possible to deal with a unidirectional problem in non-linear transient thermics and to verify that a change in liquid/solid phase is taken into account by *Code_Aster* by introducing the latent heat of fusion via the volume enthalpy. The solution is analytical and involves error functions :math:`\mathrm{erf}` and :math:`\mathrm{erfc}`. The problem is treated in plane and volume cases.

For the models presented here, the differences in the results obtained by*Code_Aster* are between 1 and 4% of the analytically calculated reference.
